磁共振成像在宫颈癌分期中的应用

Magnetic Resonance Imaging in Staging of Cervical Cancer

宫颈癌筛查工作的开展使其病死率下降。但近年宫颈癌发病率呈稳步上升和年轻化趋势,提高宫颈癌临床诊治水平仍需进一步探讨和解决。宫颈癌正确分期对制定合理治疗方案、判断预后起重要作用。2009年国际妇产科联盟(FIGO)重新修订子宫颈癌分期,细化其中一些概念,但单纯应用临床术前分期仍有难以明确的问题。影像学检查在宫颈癌诊断中广泛应用,特别是磁共振成像(MRI)技术的应用更为临床提供了准确信息,凸显出MRI宫颈癌分期联合临床FIGO分期的重要性。MRI有直观显示肿瘤的优势,可准确评估宫颈间质浸润的深度、肿瘤体积及淋巴结转移情况等,是宫颈癌分期的重要影像学方法。

Cervical cancer is a common malignant tumor in female reproductive system,the mortality rate of it has declined due to the approach of screening which has been carried out in recent decades.However,over the last decade,the incidence of cervical cancer showed a trend of steady increase and younger,improving the standard of diagnosis and treatment of cervical cancer remains to be investigated and determined.The correct staging of cervical cancer plays an important role in making a reasonable treatment and judging prognosis.Although the methods of cervical cancer staging were revised by FIGO in 2009 and some of the concepts were refined,the problem is that the clinical methods of simple application of preoperative staging are still difficult to be clear.Imaging examination has been widely used in diagnosis of cervical cancer.In particular,the application of magnetic resonance imaging （MRI） techniques provides more accurate clinical information and highlights the significance of combination of MRI staging and FIGO staging of cervical cancer.The visual display of tumor is the advantage of MRI,accordingly,depth of cervical stromal invasion,tumor size and metastatic lymph node involvement can be assessed accurately.Thus,MRI techniques are significant imaging methods of staging of cervical cancer.
